Bunker survey jobs conducted by AIM Control third
party inspection to Charter Party, Ship Management, Ship Operation, Bunkering
and Ship-owners as well other parties who need to have the exact quantity
and volume figure to expose this to others identification of marine vessels and
ships upon ON-HIRE / OFF-HIRE / BUNKERING.

DETAILS
What is AIM Controls Bunker Survey? The survey is
carried out to measure and ascertain the quantity of Bunker on
board at the specific time. This survey is produced the report that
states the amount of bunker, usually Fuel Oil (FO) and Diesel Oil (DO), and
sometimes Lubricating Oil (LO) is included.
In this post limits to how to conduct the
Bunker Survey on the ship tanks only.

Steps for AIM
Controls Conducting Bunker Survey
·
Identify and records the number and Depth
of Tank, Reference Height, and Measuring Method recommended to use (Ullage or
Sounding) for each Oil Tank. Sounding is determined the level of liquid tank
from the bottom of the tank to the liquid surface (typically applied for light
liquid). Ullage means to determine the level of liquid of tank by measured the
empty space from top of the Tank (the mouth of Sounding Pipe)
to the liquid surface (typically applied for heavy liquid). The
both methods will point to the same result.
·
Record the Last Bunker Report, Time and
Place of last Bunker supplied, includes the Oil density.
·
Records the quantity of bunker onboard when
the ship arrives at Port (arrival Condition) as per Engine Log Book.
·
Checking the accuracy of the Sounding Tape,
it is recommended to use your own Sounding Tape. In case we used Ship’s
Sounding Tape, please checking the tape.
·
Sounding each Oil Tank and records the
level of Oil on the tank. Attached the sounding Tape with Oil Paste to make
easy and clear to show of oil level (recommended for Light Oil).
·
Check the Ship’s Draft Marks to get the
Ship Trim for Trim correction, and check the ship Inclination or Listing for
List Correction, that is required to calculate the Tank Quantity Table.
·
Taken Oil sample, check temperature and oil
density, for the accessible tank only. The Service and Settling Tanks are not
accessible due to the oil on that tanks were in heating condition at the high
temperature. We could records the tank gauging for determining the quantity,
the temperature at the thermometer available on each tank, and the Oil Density
from the Engine Log Book. If you could not taken the oil sample for checking
density, it is recommended to calculate the Density Commingle, by means the
Combine Density between two Oils (Old and New Oils) that has mixed on one tanks
which they have different in Density. Where it is approaching the actual oil
density, the pattern is {(Old Oil Quantity x Oil Density / Total Oil on Tank) +
(New Oil Quantity x Oil Density / Total Oil on Tank)}.
·
Calculations, this stage will involved the
Sounding level of each tank, Ship’s Trim and List, Tank Quantity Table
(provided by Ship’s Chief Engineer), Oil Density and Temperature, ASTM Table
54B to ascertain the Volume Correction Factor (VCF – to convert from Cubic
Meter to Kiloliter) and ASTM Table 54B for Weight Correction Factor (WCF – to convert
from Kiloliter to Metric Ton).
·
Example to calculate Density Commingle: FO
Tank No. 1 C, total oil on tank 400 Cu.M, Old Oil 200 Cu.M with density 0.9870,
and New Oil 200 Cu.M with density 0.9720. Density Commingle = {(200 x 0.9870 /
400) + (200 x 0.9720 / 400)} = 0.4935 + 0.4860 = 0.9795.

Issued the Tank Sounding and Bunker Report.
